Abstract (en)
[origin: EP2839972A1] A tire is disclosed having a circumferential tire tread and an underlying and supporting carcass comprising at least one uncured cord reinforced rubber ply (3) extending from spaced apart tire beads through the crown of the tire and a preferably pre-formed laminated tire innerliner (2). The laminated tire innerliner (2) comprises an alloy film (4) cohesively bonded to said uncured cord reinforced rubber ply (3), wherein both sides of said alloy film (4) contain an RFL adhesive coating (5A, 5B), and wherein said alloy film (4) is cohesively bonded to said uncured cord reinforced rubber ply (3) by said RFL coating (5A, 5B) on said alloy film (4). The laminated tire innerliner (2) is a circumferential innerlayer of the tire having its ends joined together in an overlapped configuration to thereby form an RFL cohesively bonded splice (6). The alloy film (4) comprises at least 50 percent by weight of a thermoplastic polymer comprising at least one of nylon or polyester terephthalate and a second or minor portion of at least one of a dispersion of elastomer domains comprising at least one diene-based elastomer, and a polymer comprising at least one of polyalkylene glycol, polyoxyalkylene diamine and copolymers thereof. Also, a method of preparing a tire is disclosed.
